Warped Image when rendering on a curved surface

Registered forum members do not see this ad.

I do a ton of rendering for my work. We have many curved surfaces within our product line. My problem is that, A lot of times my materials (jpeg's) warp and blur when added to a curve. My guess is it has something to do with the UCS orientation because if i rotate the curve to be parralell with the current UCS, the material shows up how it should, Until i change the UCS back to world.

Same Image material, Surface on left is curved and surface on right is flat. Warp.jpg
whats going on here?
